Product Description

When the battery icon is coloring red, click in the 3G JUICE , start smiling. Double the life from 10 to 100% in 2,5 hours with this extra battery which easily clips on your iPhone (also iPhone 4), iPod or iTouch. Featured in Gizmodo (NL) and New York Times (US).
If you normally can talk 6 hrs with your phone, now you can talk almost 12 hours. If you surf for 4 hours, you get almost another 4 hours.
We prefer to use this comparison because claims like 'up to 50 hours extra power' are measured under extreme conditions: all features are off and the 3G radio has to have a great reception. That's just not normal life.
The 3G JUICE charges the battery of your iPhone to 100% and can be reloaded afterwards through a mini-USB cable (included) or your normal iPhone-charger.
Be assured, the product output voltage/current is designed per Apple specification. It will not damage your iPhone/ iPod. It has a certification from Apple, called 'Made for iPhone'
You can throw a 3G JUICE in your glove department (put it on OFF), forget it for a whole year and it will still give your iPhone another boost.
Supports the new iPhone 4
The high capacity, compact size Li-Polymer in 3G JUICE is small (62×60x12.9 mm) and gives your iPhone 3G a steady 5V. You can also charge any iPod with a 30 pins connection with it.
Ideal for long trips or as emergency battery.
With new power board + improved response to extreme temperatures
This version has a strong 2A capable IC, which means that any peaks of your iPhone can easily be absorbed.
We're extremeley proud about the stability of this version. Because we use li-polymer, there is no memory effect. Because of the 2A circuit, power doesn't fade away after a few months.
Comes in a black box with USB-cable. Manual is provided online only, we're a green company.

Pros -Works as advertised.Charges 3G in less then 2.5 hours while using it with 3G and GPS running at times.Slick design. Comes with a protective cover and fits easily in your pocket.Sits flush against the base of iPhone.I researched all the competition and this one has much higher battery amperage.Made for iPhone/iPod Seal.Light to carry.Packaging is very well done and so is their website.

ConsNo battery remaining indicator - (developer said this will come in the future)No pass-through charging capability (also may come in the future)Can fall out of 30 Pin slot when holding upright and jarred. Think this will happen to all external batteries due to design of 30 Pin connector. Simply grip part of your hand around battery and iphone when using.

ConclusionThis product works as advertised. Should have been the battery Apple put inside the phone!Blows away the competition in amperage and for the same price.Developer is extremely quick to respond to questions (a big plus!) and open to suggestions.I have my iPhone mounted on my bicycle and often run GPS. Without this external battery, I have to keep an eye on battery life. Not any more!

First let me say I like it, but if you plan on using it with your iPhone and your iPhone has protective hard case (and some rubberized cases) it will not fit into the iPhone unless you remove the case. I solved this by purchasing an adapter for $25-so add that to the cost of the 3G Juice if you use a hard case or a rubberized case in some instances. It definately will not work with an OtterBox case.

This item was highly recommended by an Apple Genius on the day I picked up my 3GS and I ordered from amazon that night. Very slick design and attaches to the phone very securely, even when using a chargeable case (Griffin Reveal, another good Apple rec., BTW).

It truly does double the battery life and recharges in less than 3 hours USB; have not tried AC yet. Love the on/off switch and cap. Now I can feel confident leaving 3G, Bluetooth, location services and Push on all day, since I have this as a backup. I didn't want to hassle with car charging, and this is an elegant way to ensure ample power all day long no matter what the usage.

Just wanted to add another positive review to encourage customer investigation of this product. Their website is very communal, their brand story is interesting and this product really exceeded my expectations. It is easy to use and convenient to carry, has wonderful design relative to phone, and really helps me feel more secure when I'm traveling or heavily using my I-phone. The 3G JUICE really increases the value of my phone since the battery is unfortunately its biggest liability, and I don't think I could live without it now. Highly recommend!

I originally bought the G3 Juice because of its sleek modern look. It fits perfectly with the iPhone. Its a conversation piece. The battery served me well, but it suddenly stopped charging. I contacted G3 Juice's customer service and they responded immediately. Within 24 hours I not only had a probable cause for my problem, they informed me that they would be replacing the product. They gave me a delivery date. All I had to do was return the defective battery. They even offered to refund the shipping charges if they were exorbitant. These charges were minimal so I declined. Not only did a new battery arrived on the date promised, TWO batteries arrived. I informed customer service that I had received two and inquired how to return one. They told me to just enjoy the extra battery. This is a company that stands by their product and goes an extra step to make their customers happy. I will definitely buy their products again.

I purchased this product just before I went to Mexico a little over a month ago. I wanted to watch movies on the four-hour plane trip and have backup battery power that was light and easy to use. The 3G Juice worked great! After returning from my trip, I decided I didn't need a charger for my car because I can just pop the 3G Juice in my purse for those long road trips. It's lightweight and not bulky. The design compliments the iPhone and it charges quickly. Support appears to be great also (though I haven't needed it) and the Web site is quite user-friendly. I'd definitely recommend this product for any iPhone user who is on the go and enjoys traveling lightly.

When was the last time you purchased a product which HUGELY exceeded your expectations?When was the last time you did business with a company where the President personally responds to multiple messages?And finally, when was the last you took a long trip without carrying car adapters, airplane power plug converters, or heavy brick-type backups that sapped the joy of traveling with a portable device?.

Many suggest that you turn off the Apple iPhone 3G's multiple features to conserve battery power. Hell, those power - draining services are the reason I bought the iPhone 3G in the first place!

SOLUTION:I bought two 3GJuice batteries. Each takes up about the space of two matchbooks and are just as light.3GJuice 3GJUICE Black 1800 mAh/2A DeLuxe Version. iPhone/ iPod Battery Charger. External Clip. is very much an Apple - like company.I am just as happy with this product (not to be confused with the supposedly established firms that offer products with similarly -sounding names) as I am delighted with the iPhone 3G itself!Works on all my iPods, too.

I draw crowds at the Apple store in Stamford, CT (USA) when I take the battery out to show to others. Judging by the response, you would be very lucky to get one.
